R&S®CMW500 Wideband Radio Communication TesterBenefits and key features

Notes:Some aspects of the functionality described on this page require additional hardware and/or software options.

The 3GPP Rel. 8 mobile radio standard is still being developed. The functionality of the R&S®CMW500 LTE protocol tester is continuously being developed further to reflect advancements in standardization as well as industry requirements. The ac-tual scope of functions available for the R&S®CMW500 UMTS LTE protocol tester is provided on request.

Developed for early LTE development

Multiple interfaces to the device under test 1)

The R&S®CMW500 for LTE protocol tests offers multiple interfaces for communicating with the protocol layers to be tested in the wireless device (DUT). Depending on the DUT's level of integration, a purely software interface, a digital I/Q interface or an RF interface must be used. Multiple powerful Ethernet interfaces interconnect the R&S®CMW500 with application servers for testing user plane data services such as FTP, UDP, VoIP.

Software interfaceThe software interface requires the protocol software of a wireless device to be linked to the virtual physical layer supplied by Rohde & Schwarz by embedding a C++ library. This means that users can no longer discern from the pro-tocol layers above whether a real or virtual physical layer is being used. The network simulation speed can be adjusted to the DUT's requirements by means of soft timers.

1) Some aspects of this functionality require the addition of hardware or software options.



Digital I/Q interfaceThe digital I/Q interface connects the tester to the DUT's baseband. The digital I/Q data is transmitted at variable speed in accordance with the Rohde & Schwarz digital I/Q standard. Thus, the data is compatible with other Rohde & Schwarz instruments such as signal generators and analyzers. The I/Q signal can be adapted to other specifications via external adapters.

RF interfaceThe RF interface is the most common and simplest way to connect the wireless device to the protocol tester. The air interface standardized in the 3GPP specification is used. Tests carried out with this interface require a protocol im-plementation that has been fully integrated into the base-band and the RF.

The interface used is transparent for the protocol layers above and the tester's software modules. The user can therefore switch between interfaces without having to modify test routines and software tools.

TCP/IP interface Gigabit Ethernet supports high LTE data rate requirements, which means that IP data tests and performance tests (e.g. throughput) can be carried out without any problem. Comprehensive logging of IP traffic together with C-plane messages are integrated in a message analyzer tool.

Layer 1 testTo make functional testing of the LTE physical layer pos-sible, future options will provide basic measurement func-tions. These functions are carried out in test scenarios that are either predefined or easily created by the user.

The functions will include the following:

Tests for verifying physical layer procedures, e.g. CQI, J

timing and power control, RACHTests for layer 1 performance measurements, e.g. J

receiver and throughput performance

Defining testsSignaling scenarios are defined in simple C++ routines. Two application programming interfaces (API) are avail-able for this purpose: the low-level API (LLAPI) and the medium-level API (MLAPI).

The LLAPI provides users with direct access to the proto-col layers. This means that users enjoy maximum flexibility especially required in protocol development.

Signaling scenarios built on the RRC protocol layer are defined using the MLAPI. To minimize the amount of pro-gramming involved, all protocol layers below are automati-cally configured from the contents of the layer 3 messages – thus saving a significant amount of time for the person creating test scenarios. This automatic configuration can be deactivated and all layers below configured manually.

The individual protocol messages are conveniently created by means of the message composer software tool both in the LLAPI as well as in the MLAPI. This tool displays the messages in a straightforward, easy-to-read manner.

A collection of signaling scenarios for developing layer 1 and the layers above is available in the source code, and the user may modify or expand them as required. The test scenarios may be applied no matter which DUT interface is used. This means that the R&S®CMW500 can be used throughout all phases of development.

Shorter development timeEfficient software toolsPractice-proven software tools for protocol tests help the user efficiently operate the R&S®CMW500. Signaling tests consist of three phases:

Defi ne test J

Run test J

Analyze test J

A customized software application is available for each phase.



Parallel testing during each phase of developmentThe cost-effective virtual software tester enables users to perform tests on the protocol stack software at the same time hardware is being developed. Therefore, dependen-cies between the individual development teams can be reduced.

Reuse of test equipment and test routines in all phases of J

developmentFunctional tests and regression tests in parallel during all J

phases of development

Performing testsThe project explorer controls the sequencing when test scenarios are run. This involves configuring and starting test campaigns as well as generating test reports.

Graphical configuration of tests, also covering various J

The R&S®CMW500 may be used throughout all phases of development owing to the following:

Programming interfaces tailored to the purpose of the J

testUniversal software tools J

Both in the protocol as well as in the RF and application enabler conformance test, the R&S®CMW500 will play a leading role. The hardware and software used in the devel-opment of the protocol stacks is already prepared for use in conformance testing.

Negative testingThe R&S®CMW500 provides a 3GPP-compliant reference implementation of layers 1, 2 and 3. Yet the LLAPI also allows users to simulate specific malfunctions on the net-work end in order to test the stability of the DUT under these conditions.

RF measurements simultaneously with signaling Future options will enable users to utilize the RF measure-ment functionality of the R&S®CMW500 even as signaling scenarios are being run. For example, if the DUT malfunc-tions, basic functions and parameters may be analyzed at the physical layer.

Linking to other Rohde & Schwarz LTE measuring instrumentsThe RF interface can handle additional measurements if the R&S®CMW500 is combined with other LTE measuring instruments such as the R&S®FSQ or the R&S®SMU200A.

In addition to the RF interface, the I/Q interface may also be utilized since it uses the same standard. I/Q signals can then be exchanged between Rohde & Schwarz instruments without any problem.

For performance measurements under fading conditions, an R&S®AMU200A can be integrated via the digital I/Q i nterface.
